Links

Link discovery fixtures covering standard anchors, nofollow variants, JavaScript-built links, hidden links, iframes, malformed markup, and a 10,000-anchor page.

Fixtures for link extraction and discovery. Every deliberate anchor points at one of three real 200 target pages under /tests/links/targets/, so a crawler that follows a discovered link always lands on a verifiable page.

Families:

• Standard anchors: plain internal links, a single controlled external link, relative/root-relative/protocol-relative URL forms, a base href override, and an image-wrapped anchor.
• Empty and broken: anchors with empty, missing, whitespace-only, and scheme-only hrefs that must not become crawl links.
• Nofollow family: rel="nofollow", rel="ugc sponsored", and a follow/nofollow conflict on the same target.
• JavaScript links: onclick-only navigation, string-concatenated hrefs, AJAX-injected anchors, pushState URL mutation, and an anchor inside an open shadow root — all browser fixtures with raw and rendered markers.
• Hidden and non-standard: data-href spans, noscript anchors, and anchor markup inside comments and template elements.
• Iframes: a same-domain iframe with a linking document, and a cross-domain iframe served from the controlled cross-origin subdomain.
• Edge cases: whitespace-padded and percent/entity-encoded hrefs, invalid nested anchors, and a streamed page of exactly 10,000 unique anchors capped to four concurrent generations.

The high-volume and cross-origin fixtures are risky-manifest, direct-entry only; the rest are safe for broad crawling within the fixture domain.
